MVC :: Passing Data From View Back To Controller
Sep 23, 2010
I have following situation - I am pasing user info object from Controller to View. It contains GUID UserID, which i dont want to be seen on page. So I removed every Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc... from generated View source. And because of this when Html.BeginForm() returns that object back to Controller all values is there but UserID is lost??
If I leave Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc.. in View everything is fine. But I dont want to show UserID? Where is the problem here?
<%= Html.LabelFor(model => model.C__User_Id) %>

I have setup an httppost that sends a string into my controller, searches for some results using linq, and then sends the results to a view. In debug stepping through the code I can see the data that I am looking for being passed into the return view statement, but the page just appears to refresh (it doesn't render the view as expected with the result). why my controller fails to redender the view? (note: I didn't include the view because I can send a ToList() to it without an issue. For example, return View(_entities.Persons.ToList());
[HttpPost]
public ActionResult RenderSearch(string usersearchtext)
{
if (usersearchtext != null)
{
var search_results = from s in _entities.Persons
where s.Description.Contains(usersearchtext)
select s;
return View("SearchResult", search_results.ToList());
}
else
{
throw new NotImplementedException();
}
}

I have a dictionary I'm passing to a View. I want to be able to pass the values of that dictionary back to a Controller action from this same View. Is there anyway this can be accomplished without using a form? The situation is that I need to be able to pass these back to a controller action that is called when a user clicks an ActionLink from the View, and in my experience an ActionLink cannot be used to submit a values of a form, i.e. I've only been able to submit values of a form using the form's submit button. Unless there's a way to use an ActionLink to submit values in a form.Controller Action passes Dictionary to Controller in ViewData:
public ActionResult ModifyNewCrossListing(FormCollection form)
{
Dictionary<int, string> prefixlist = new Dictionary<int, String>();

I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?

I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code?
<script language="javascript" type="text/javascript">
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
var selectedID = $(this).val();
if (selectedID != "New Vendor Id") {
//$.post('Url.Action("DropDownChange","Refunds")', function(result) {
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
});
}
});
});
This is the code in my controller;
public JsonResult DropDownChange(string dropdownValue)
// This action method gets called via an ajax request
{
if (dropdownValue != null && Request.IsAjaxRequest() == true)
{
paymentApplicationRefund =
cPaymentRepository.PayableEntity(dropdownValue);
paymentApplicationRefund.Address1.Trim();
paymentApplicationRefund.Address2.Trim();
paymentApplicationRefund.Name.Trim();
paymentApplicationRefund.City.Trim();
paymentApplicationRefund.Contact.Trim();
paymentApplicationRefund.State.Trim();
paymentApplicationRefund.Zip.Trim();
return Json(paymentApplicationRefund,"application/json");
}
else
{
return null;
}
}

I am working on an MVC application and I have an index view where I pass model from controller to index view. The index action has no parameters. Now On view I have a jquery calendar. I want to change all the data on view when a date is selected. do I need to use different action method for this as current action method doesn't have parameter. or I can use same ?

I've been going at this for several hours and I simply cannot find the solution.
I want to get some data from my user. So first, I use a controller to create a view which receives a Model:
[code]...
The rest of this controller does not matter since no matter what I do, the count attribute of Request.Files (or Request.Files.Keys) remains 0. I simply can't find a way to pass the files from the form (the Model passes just fine).

I would like to pass List<SelectListItem> (not selected item but the whole "List" object) back to controller.
for example in my GET controller i would have this
ViewData["list"] = some select list from repository;
then on post I would like to get the list back from view..pretty much i'm trying to use ViewData["list"] as storage..this way I would use ajax to remove or add items to/from the list.

I'm having problems passing values from the controller to the view. I created a boolean variable to use as a flag and want the view to render some html based on whether its true or false.
Unfortunately ViewData doesn't look like it can pass boolean values. I should be able to pass any datatype to a view (string, int, bool, etc...)

I need to pass a list of Entity Objects from Controller to View but not put it in the Model context. It is the users homepage, but I am putting a list of alerts on the users home page(somewhat like facebook). So I need the User Context as the Model I pass but need to pass the Alert model as well so I can show the list of alerts.. How would I do that? The code below is what I have so far..

I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
[Code]....
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.

I am new to MVC, and trying something and got stuck somewhere in between.I have a user control there I have three textbox html type(ID, Lastname, firstname) and a submit buttom. I set the button like
<input type="button" value="Search"
onclick="location.href='<%= Url.Action("action", "controller") %>'" />
I have called this usercontrol on some view through
<%= Html.Partial("ucName") %>
Now on pressing that button(on user control) I need to pass the data from these textboxes to controller again to some specific action(Http Post action). By using this data I want to do some database interaction and storing the result in a dataset and pass this data set to same view again to show up in some Grid.I know the first part in conventional Asp.net can be done by raising the event through delegate but don't know how to do that in MVC.

This may seem simple to a seasoned coder, but I'm all wet-eared and new to MVC, and trying to wrap my head around it is driving me nuts. I have completed the Nerd Dinner and MVC Music Store tutorials, and seem to be grasping the basics... Well, sort of... It just seems that every new idea I have requires hours of searching with Google.
As it stands at the moment, I have a static DateTime field that is populated by using DateTime.Now. What I need to implement is a master TextBox (JQueryUI DatePicker) at the top of the View that will enable the user to overwrite said DateTime.Now if required.
Here is a hypothetical situation:
Controller
[Code]....
Site.Master
[Code]....
View
[Code]....
I thought of using a variable to override the default date if the user selects a master date, but can't figure out how to implement it.
I can get it to work if I use a static string, like so:
[Code]....
Is there any way to pass the value of the master datepicker (txtDateTime) from the View back to the Controller? I've heard mention of TempData, but can't seem to find a similar scenario.
I'm sure I'm just missing something really obvious, so if anyone could explain it to me really s-l-o-w-l-y, that would be cool.
I'm praying that this isn't another of those situations where "MVC doesn't work that way" or "It needs more cowbell", 'cause then I'll pack it all in and go play WoW D:

I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there. After I read the objects, I display the booking details and I generate a list of cancelation reasons in the following way:
[Code]....
The code above generates a list of cancelation reasons.How do I pick up the selected ReasonId from the list?
I need to generate a link that will contain the bookingId and the selected reason for canceling the booking.I can get the bookingId out easily since it's stored in the Model...but how do I go about the selected ReasonId?

(I think) with using a data bound Custom Control on the server to get hold of my data (it will be part of a larger dataset) and to ultimately pass updates to the database. The bit I'm researching at the moment is passing that data to and from the client.One way to pass the data to the client is to use JSON within the Pageload event to construct a set of Javascript objects (one per row in the data). Is that the best way, or am I missing something?
Then, after the data has been manipulated on the client, I need to pass the rows back again so that the server side code can pick them up and process the updates. I've seen a suggestion on here that a hidden text field is one way to do that. Is it the best?Neither of my approaches seem to be at all elegant - and I suspect that I am missing something fundamental in ASP .NET AJAX!

[Code]....

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).
Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?
Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

I'm a php programmer (code igniter) but interested in learning ASP.net MVC, I have a few question regarding this new exciting framework In php codeigniter's controller I can easily catch a post variable using

In comparison in ASP.net MVC we can create an action method that will accept post variable (but the parameter can get very crowded if we're passing a lot)
[Code]....
Or using FormCollection
[Code]....
Is there a way to catch post variable in ASP.net that looks like php's codeigniter? I mean not by adding the parameter, because I wanted a controller method that is flexible in receiving post request A controller that can accept and process any post request like in php (where we don't have to put that parameter to the controller method, we just call them
